Geekworm NASPi offering an easy and fast way to create your home media center and building NAS or Web server for your raspberry pi 4 with a 2.5 inch SATA HDD/SSD..
NASPi is composed of three parts: X823 storage shield, X-C1 adapter board, heat dissipation system(include X823-A3 metal fan bracket and 4010 PWM fan), and they will be packed into a ALU-case to get a complete NASPi.
How to Power: 5Vdc +/-5% , ≥4A (Via Type-C Port of X-C1).
Recommend to use Geekworm UL listed 5V 4A Type-C power adapter (ASIN:B09J856PND)..
SSD Thickness Description: NASPi supports SSD with a thickness not exceeding 9.8mm, most 2.5" HDD/SSD on the market are only 7mm thick..
How to Make the PWM Fan Work: PWM fan needs a PWM signal to start working, so need to install shell script (refer to above wiki), If the fan does not work in third-party OS, only remove the yellow wire of fan to let the fan run immediately..
